We identified multiple extraintestinal cystacanths during routine postmortem examination of 3 small Indian mongooses and 2 African green monkeys from the Caribbean island of St. Kitts. In mongooses, cystacanths were encysted or free in the subcutaneous tissue, skeletal muscle, or peritoneal or pericardial cavities, whereas in the monkeys, they were in the cavity and parietal layer of the, tunica vaginalis, skeletal muscle, and peritoneal cavity. Morphological, histological, and molecular characterization identified these cystacanths as Oncicola venezuelensis (Acanthocephala: Oligacanthorhynchidae). There was minimal to mild lymphoplasmacytic inflammation associated with the parasite in the mongooses and moderate inflammation, mineralization, hemorrhage, and fibrosis in the connective tissue between the testis and epididymis in 1 monkey. We identified a mature male O. venezuelensis attached in the aboral jejunum of a feral cat, confirming it as the definitive host. Termites serve as intermediate hosts and lizards as paratenic hosts. This report emphasizes the role of the small Indian mongoose and African green monkey as paratenic hosts for O. venezuelensis . |
